Were 20mm Hispanos used on P-38's Reliable?

Tony Williams there really knows his stuff. I do give the .50 caliber M2 series more credit than he does though. It worked for what we needed it to do.

Wasn't there a F6F-5 variant that had two 20mm Hispanos and four .50 cals? I think that would be a rather ideal armament for most situations.

A bit off-topic but did any P-38 variants with the 37mm cannon see combat? Considering the tally I've gotten in IL2 with the 37mm cannon on the P-39, I'd be interested to learn what pilots and engineers thought of this weapon.
